A perfectly normal acquisition, if a little steep. The real twist is that Harpan LLC is owned, operated, and staffed by a pair of brothers — Austin-based Tim Oswald and his Chicago-area brother William.

Analyst firm App Annie shows that Solitaire, Harpan's flagship app, is currently the number-one card game on the Apple iOS App Store, and bounces in and out of the top 10 games overall. It's an advertising-supported free game that's described in its App Store listing as having "crisp, clear graphics, and a straight forward [sic] layout."

Harpan also makes three additional card games, including Pyramid Solitaire, FreeCell, and Spider Solitaire, all offering a similar aesthetic. All of his games are available for iOS and Android.

Notably, Harpan isn't the Oswalds' only venture — Tim's LinkedIn profile connects him to "Tim O's Studios," a separately-listed developer on the Apple App Store that makes simple apps and games like "Calculator%" and "Guitar Tuner."
